According to Tokyoflash Design Studio ”To read this watch is actually not as hard as it looks. This “always on” mirrored LCD display watch shows the time in hours and minutes in separate sections, top and bottom. Take a look at the second image below for simple explanation. The 2 buttons on the right side of the watch are used to display the time or illuminate the display. Each part of TokyoFlash Kisai 3D Unlimited watch has been designed individually such as the case, strap, and the programmed LCD display. It’s a universal watch, thanks to its adjustable polished stainless steel strap making it suitable for small or large wrists. So far, this watch design is the thinnest design available from TokyoFlash with only 8.6mm thick”.
